<p>Nodes have two properties: a name, and whether or not they're latent. To edit these properties for a particular node,
    double click that node, set the properties the way you want, and click &quot;OK.&quot;</p>
<p>Consider the following example.</p>
<p><img height="541" src="../images/editing_nodes1.gif" width="564"></p>
<p> Here we have a graph using default node names X1, X2, and X3. We would like this to read &quot;Heat, a latent
    variable, causes volume and pressure,&quot; so we need to change the name &quot;X3&quot; to &quot;Heat&quot; and
    make it latent. Double clicking X3, the following dialog comes up:</p>
<p><img height="540" src="../images/editing_nodes2.gif" width="564"></p>
<p>Clicking &quot;OK,&quot; the result looks like this:</p>
<p><img height="542" src="../images/editing_nodes3.gif" width="564"></p>
